Did you know that the majority of DLL errors are caused due to missing DLL files?
If a DLL file is missing from your computer then you will receive an error message every time a program or process calls upon that DLL file.
Listed below are common error messages that you may encounter–
“mfc80u.dll file is missing.”
“mfc80u.dll file not found.”
The job of resolving a missing DLL error becomes easy once you know what caused the DLL to go missing in the first place. Mentioned below are two common reasons due to which a DLL file may go missing.
- Deletion of the DLL file by mistake.
- Deletion of the DLL file by malware infection.
Depending on the cause of the missing DLL file, you may perform the following steps to fix the error:
Restore the deleted file from the Recycle Bin
If you have accidentally deleted a DLL file and the file is still present in your Recycle Bin then to repair the DLL error, restore the deleted DLL file.
The scenario becomes complex if the file has been removed from the Recycle Bin as well. In such a case you may use a third-party file recovery tool to recover the lost file (this option should be used only if you are sure that it was you who deleted the DLL file and the file was functional before its deletion).
Remove malware threats from your computer
If you did not remove the DLL file but the file is still missing, chances are your PC is infected with malware.
Malware programs are known to delete or alter DLL files and cause errors, such as error msvcr80.dll. Run a malware scan on your entire computer using an advanced antimalware tool and remove any found threats.
After you have secured your system you can perform either of the steps mentioned below to procure the missing DLL file:
Run the System File Checker (SFC) command – If the DLL file listed in the error message is a core Windows file, run the SFC command to procure a new copy of the DLL file from your Windows Installation CD.
Uninstall and reinstall the application with which the DLL file is associated – If the DLL file is not a core Windows file then determine which application uses the lost DLL file. Once you have identified this uninstall and reinstall that application to fix DLL error.
Download the missing DLL file from the Internet – In case you are not sure about the application with which the lost DLL file was associated, then download the missing DLL file from a reliable online DLL directory and save the DLL file in your System folder.
If the DLL file is present on your computer, then chances are that the cause of DLL error is a corrupt or damaged registry. To fix the issue, clean your registry with the help of a registry repair tool.
